Q. Which of the following would be consequences if the Earth's axial tilt changed from 23.5 degrees to 45 degrees?

1. Hotter summers and colder winters
2. Longer days in summer and shorter days in winter
3. Shifting of equator towards north pole

Select the correct statements using the codes given below:
Answer: Only 1 & 2
Notes: Hotter summers and colder winters are correct, as a greater axial tilt amplifies seasonal extremes. Longer days in summer and shorter in winter also result from a steeper tilt, increasing daily light duration differences. However, the equator's position is determined by Earth's rotation axis and does not shift due to axial tilt. Thus, statements 1 and 2 are correct.
